Add Ajax programmaticly -- LCIDFire --

I tried to build a test application for calling a server side method out of javascript but it just doesn't work. It seems to me it doesn't register the type for callback. I setup the web.config, like the quick sample, too.
Can anybody provide a simple example how to do this?

I tried the following:

namespace test
{
public partial class treelist : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
HtmlImage image = new HtmlImage();
image.Src = "

http://www.golem.de/_img/logo_bottom.gif

";
image.Attributes

= "test.treelist.Expand(4,
Expand_callback)";

ClientScript.RegisterClientScriptBlock(GetType(),
"expandcallback", "function Expand_callback(result){alert(result.value}}", true);
form1.Controls.Add(image);
Utility.RegisterTypeForAjax(GetType());
}

public String Expand(int recId)
{
return "blub";
}
}
}

may be you should do so:
Utility.RegisterTypeForAjax(GetType(treelist));

-- LCIDFire --

Appearently I should have done Utility.RegisterTypeForAjax(typeof(treelist));

When I do the latter I get:
{Name = "treelist" FullName = "test.treelist"}

When I try my first approach I get:
{Name = "treelist_aspx" FullName = "ASP.treelist_aspx"}

WTF!?
Does one have to understand this? I was under the impression that the content of the aspx was "partialized" into the tree class not the other way around.

If you use this.GetType() you will get the current instance which will be the ASPX page instead of the class treelist. ASP.NET will add a new class ASP.reelist_aspx for any ASPX inline code. If you use typeof(treelist) it will use the correct type. It is common ASP.NET logic, nothing to do with AjaxPro.
